CHARLES A. MOORE, OF ST. PAUL, MINNESOTA.

VENTILATING SYSTEM FOR GARS.

Application led March 23,

To all whom t may concern:

Be it known that I, CHARLES A. MOORE, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of `Minnesota, have invented a new and useful Improvement in Ventilating Systems for Cars, of which the following is a specilication.

this invention relates to improved means for more sharply deining the circulation of air throughout the entire lading chamber and walls of the car so as to more completely expel vitiated air and keep the contents of the car cool and :tree from moisture. Among further objects of myy inventions the construction of a car which is simple, ineXpensive, strong and durable and which will provide a maximum lading space. The subject matter of this application is an improvement upon the construction set forth in my companion application filed March 14, 1.912, bearing Serial Number 683,682.

In the accompanying drawings forming part of this specification, Figure 1 is a longitudinal vertical section taken upon the line X-X of Fig. 2; Fig. 2 is a cross section taken upon the line Y-Y of F ig. 1, and `F ig. 3 is a plan.

'Ihe car bod)T illustrated by the drawings is of ordinary design, being formed by outer inclosingwalls, 2 representing the loor,"3-3 the ends, 4 4: the sides and 5 the roof. rllhese walls may be constructed of wood, metal or of other suitable material mounted upon suitable frame supports in the usual manner. Inside these walls is a lining 6, which is distanced from the outer walls of the car, thus forming an enveloping space 7 through which a current of air is free to pass for assisting in Ventilating and preserving the lading in the car. Suitable. ports 8 are provided in the sides and ends near the Hoor of the car for the ingress and egress of air. In the top of the car's an ice bunker A'having a floor 9. positioned above the doorway 10 in each side and ends 1'1 having openings closed by' gratings 12 distanced remotely from the ends of the car. 'Ihe passage 7 enveloping the lading chamber opens into each end of the bunker adjacent its ends and air is free to pass from the passage 7 and ladin chamber into the ibunker or vice versa" from t e bunker Speccationof Letters Patent.

into the passage 7 and lading chamber. The roof of the car is provided with a plurality of hatchways 13, 14, 15, 16, 17 and 18 entering the bunker near each side of the car, said hatchways being remote from the ends of the car and closed by doors 19, 20, 21, 22, 23 and 24, which are hinged to the roof of the car and` adapted to be supported partly open and inclined up from the roof by means of props 25 or other suitable supporting and fasteningdevices. There are six doors and hatchways illustrated, three on each side of the center -line of the car over the bunker,

`two of the doors being hinged to open in one direction and the remaining door in the opposite direction on one'side of the car. This order of arrangement is reversed on the other side. The angle of inclination of these doors when open and this arrangement are such that/two of the doors such as 20y and 21 on one side of the car when the car moves in the direction of the arrows indicated in Fig. 1, act as scoops and direct air down into the car and the remaining door 19 on said side andone 23 on the other side act simultaneously as cowls, to prevent air entering the car through their corresponding hatchways and to deliver air out of the car. The direction of this circulation asu described is reversed when the car is moving in the opposite direction. The Hoor 9 of the bunker below the hatchways acts as a dei'lector to assist in directing the circulation of air downwardly through the hatchways and into the upper portion of one end of the car and into the passage 7, thus causing a current of air to pass downwardly along an end wall of the car and forwardly along the loorthence up and backwardly along the ceiling into the opposite end of the bunker and out through the hatchways 13 and 17. A portion of the air which is forced down through the passage 7 is free to pass into the lading chamber near the floor of the car through the ports 8 and vice versa some of the air admitted into the lading chamber is free to pass through the ports 8 into the passage 7 and out through the hatchways 13 and 17.

This circulation of air through the walls and the lading contained in the car removes vitiated air from the car and serves to evaporate moisture in the walls and cool the contents of the lading chamber. Complete and thorough ventilation is thus produced, which is advantageous; It is obvious that downwardly which to some `'degree is lpro-j duced when the deiector isuch as said floor is not employed below' the air entering pasa n accordance' with the patent statutes I A have described the principles of operation of my' invention together with the apparatus claim -as new and desireto protect by Let- 4 ters Patent is which I `now consider 'to represent .the best embodiment thereofbutrI desire to have it Iunderstood 'that the construction shown is only illustrative and that the invention can bel carried out by other means and applied to uses other 'than those above set forth within the scope of the following claims.

Having described my inventionfwhat I 1.' A car body inclosing'a lading chamber,

. said body being provided with an air inlet 2'5 and an air outlet spaced apart in its upper vportion near lmedian position between the ends ofv said body. and an overhead chamber below and'into which air is admitted by said end openings and its floor acting as a de-f fflector,inconjunction with said openings wherebyair entering said chamber through 'inlet' Iand from which air is conducted through said loutlet, 'said chamber having said. inlet is forced by the forward movechamber towardfthe` rear end in said car, then downwardly, then' forwardly over the floor ofthe car, then. upwardly near the for- Vwardend of the'car, then back along the forward upper portion in the car into said chamberand finally expelled through said outlet to the outer atmosphere.

y2. A car body inclosing a lading chamber, said body being provided with an air inlet and`l an air outlet spaced apart and located near'the median portion of the upper part between they ends of said body, an overhead ice bunker placed below said inlet and outlet having open ends forming a communication between thenbunker and lading chambers, a cover 'over said inlet slanted forwardly to act `as an air scoop .during the forward movement of the car, and aI cover over said outlet slanted rearwardly to act as anair cowl and protect said outlet from inward draft said inlet and outlet being so spaced apart as to cause air during the forward movement of thecar toA pass through said eXpelled through said outlet to the` outer atmosphere. i L -In-testimony whereof, `Ihavev signed my name to this specification, inthe presence of ment of the car, longitudinally from said -two subscribing witnesses. `CHARLES A.
